Sub pico-second pulses in mono-mode optical fibers with Triki-Biswas model
The model proposed by TB is presented as follows
$$\begin{aligned} Q_t+i\textit{a} Q_{\textrm{xx}}+b\left( |Q|^{2 n} Q\right) _x=0. \end{aligned}$$
In order to obtain exact solution to Eq (1), we apply the traveling wave transformation (3), and…
